scrape ASIN from amazon URL using javascript

Question

Assuming I have an Amazon product URL like so

http://www.amazon.com/Kindle-Wireless-Reading-Display-Generation/dp/B0015T963C/ref=amb_link_86123711_2?pf_rd_m=ATVP

@Gumbo: Your code works great!

//JS Test: Test it into firebug.

url = window.location.href;
url.match("/([a-zA-Z0-9]{10})(?:[/?]|$)");

I add a php function that makes the same thing.

function amazon_get_asin_code($url) {
    global $debug;

    $result = "";

    $pattern = "([a-zA-Z0-9]{10})(?:[/?]|$)";
    $pattern = escapeshellarg($pattern);

    preg_match($pattern, $url, $matches);

    if($debug) {
        var_dump($matches);
    }

    if($matches && isset($matches[1])) {
        $result = $matches[1];
    } 

    return $result;
}
